1. Model of the Ang-1 pathway in early lung development.
Model of the Ang-1 pathway in early lung development. Proposed model of the Ang-1 pathway in early lung development (E12.5 to E15.5) hypothesizes that Ang-1 (red) secreted by the distal lung bud acts in a trophic fashion on progenitor vascular endothelial cells expressing receptor Tie-2 (green) in the mesenchyme to induce downstream signaling and stabilization of the nascent vasculature. In later development (E18.5 to postnatal), the relationship between Ang-1 and Tie-2 contributes to the stabilization of the primary blood vessels associated with the central airways in the maturing lungs. PN, post-natal.
